“Wow! The Sandbox is a real killer of a novel…Devious plot twists, relatable characters, and insights into AI technology that are truly chilling! Highly recommended.”

“Andrews and Wilson have outdone themselves in their genre-bending new novel, The Sandbox. Mixing classic sci-fi themes—think Philip K. Dick and Robert Heinlein—with their unbeatable pacing and military action scenes makes this a nonstop thrill ride. But what really makes this a standout novel is the bad guy. In the sentient AI system named Charlie, Andrews and Wilson have created the most disturbing and frightening antagonist since Arthur C. Clarke’s HAL 9000. A nemesis so powerful that he can plunge his victims into a VR-generated haunted house where they can no longer discern the digital from the real. And the scariest thing of all is that this isn’t science fiction. This is the technology that is at our fingertips today. Highly recommended.”

“Reality and virtual reality collide when a murder case evolves into a nightmarish battle that pits a homicide detective, an ex–Green Beret, and a computer genius against ‘Charlie,’ a sinister artificial intelligence program in an epic struggle for nothing less than control of men’s minds. The Sandbox proves beyond doubt that Andrews and Wilson, authors of the bestselling Tier One series, are truly the masters of suspense.”

“[Andrews & Wilson] bring the gritty realism and action of their covert-ops thrillers to the grounded sci-fi world of AI. A nonstop roller coaster of a read!”

“Andrews and Wilson have crafted an intense and eerily timely techno-thriller; it’s Silence of the Lambs meets HAL 9000 from 2001: A Space Odyssey. The series will make readers think twice before asking Alexa or Siri a question, but they’ll want to play in this sandbox.”
